I think my speakers are a perect match for the new Firstwatt amplifier. They worked very well with a Zen V4 and Mini A.
I am using a Le Monstre right now. It is sounding excellent. My speakers are 5' tall folded TQWT's with 15 ohm PM2A. I have PM7A and PM6A, but in these cabinets the 2A has a little stronger highs to balance the big bass.
I just set up my digital RS SPL meter and the first Stereophile CD to check frequency response in room.

12' from speakers,meter same height as driver 43" centered between speakers, both channels playing

When I saw you casually refer to the first amp from First Watt as F1, I thought it quite appropriate (and enjoy the analogy). I'm a huge Formula 1 fan and have seen a number of sites using 'F1' shut down via copyright problems. Not that you haven't researched it, I was just saying something I've seen.

In my stomach, I felt that F1 via Nelson Pass is probably the same for me as F1 via the FIA. That is a huge compliment for those who don't enjoy what Formula 1 is to me.

It's crazy. Just look at how the World Wildlife Fund was able to force the World Wrestling Federation to change its name because they share the same acronym.

On the other hand (wow, some lady on TV was saying the exact same thing as I was typing that), Tag McLaren had an "F1" line of electronics.

Considering that there will only be 100 F1's available, they'll
probably be gone before anyone notices.

Regarding the most ideal speaker, so far the best examples
are Lowthers, but I've seen some improvement in all high
efficiency wide range drivers - the more sensitive, the better.

So far all the data is on sealed boxes of various sizes, but
Chris and Matt should finish the horns next week, and we are
also planning on including the Lowther Medallion enclosures
as rear loaded horn examples. I expect rear horn loading to
require some adjustment of the RC parallel loading networks,
but otherwise no problems.

We will launch when my PM4's arrive and after I get back from
Sea Ranch. At that time I will also post an article on the results
of all our driver tests, and I'm sure you will find it interesting.
